I may have answered some of my own questions on the transmission, yoke, and clutch.
I pulled the tag off the transmission and cleaned it off.
The numbers are : FOB 3 E 10, 72 WG BB
That tells me it is the "Ford of Britain" English tranmission.
So different number of clutch disc splines and different output shaft.
I would guess it will be the 20 spline disc.
If the numbers were FOG it would be "Ford of Germany".
Then it would be more interchangable .
It would have the 23 spline disc.
So my new question... Would a FOG German transmission bolt onto the same bell housing as the FOB English transmission?
